-.SH DESCRIPTION
-These functions return the largest integral value that is not greater than
-.IR x .
-
-For example,
-.IR floor(0.5)
-is 0.0, and
-.IR floor(\-0.5)
-is \-1.0.
-.SH RETURN VALUE
-These functions return the floor of
-.IR x .
-
-If
-.I x
-is integral, +0, \-0, NaN, or an infinity,
-.I x
-itself is returned.
-.SH ERRORS
-No errors occur.
-POSIX.1-2001 documents a range error for overflows, but see NOTES.
-.SH ATTRIBUTES
-.SS Multithreading (see pthreads(7))
-The
-.BR floor (),
-.BR floorf (),
-and
-.BR floorl ()
-functions are thread-safe.
-.SH CONFORMING TO
-C99, POSIX.1-2001.
-The variant returning
-.I double
-also conforms to
-SVr4, 4.3BSD, C89.
-.SH NOTES
-SUSv2 and POSIX.1-2001 contain text about overflow (which might set
-.I errno
-to
-.BR ERANGE ,
-or raise an
-.B FE_OVERFLOW
-exception).
-In practice, the result cannot overflow on any current machine,
-so this error-handling stuff is just nonsense.
-.\" The POSIX.1-2001 APPLICATION USAGE SECTION discusses this point.
-(More precisely, overflow can happen only when the maximum value
-of the exponent is smaller than the number of mantissa bits.
-For the IEEE-754 standard 32-bit and 64-bit floating-point numbers
-the maximum value of the exponent is 128 (respectively, 1024),
-and the number of mantissa bits is 24 (respectively, 53).)
